Calla Lily Plant Named &#39;Dozanmaca&#39;

ABSTRACT

‘Dozanmaca’ is a new variety of calla lily plant having dark purple colored spathes that produces 3-14 flowers per 14-16 cm tuber. The flower stems are about 30-40 cm in height. The leaves are green with a greyed-purple margin and have a leathery texture.

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/766,205, having a filing date of Oct. 4, 2018, and entitled “Varieties of Z. sprengeri Calla Lily Plants”, the entire disclosure of which is incorporated herein by reference.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Dozanmaca’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the cultivar name ‘Dozanmaca’.

‘Dozanmaca’ is a product of a planned breeding program, which had the objective of creating Zantedeschia hybrids for pot flower production in a wide range of colors with a large, classic flower shape. The breeding program began in 1989, and the new cultivar is a seedling selected from the crossing of Zantedeschia sprengeri seedling Z041583 (female parent, unpatented) with Zantedeschia sprengeri variety ‘Allure’ (male parent, unpatented). ‘Dozanmaca’ was selected in 2012 by the inventor in ‘t Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Dozanmaca’ by tissue culture was performed by the inventor in September of 2014 in ‘t Zand, The Netherlands. Subsequent asexual reproductions by tissue culture at the same location have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plants grown from 12 to 14 weeks in 14 cm pots in ‘t Zand, The Netherlands under greenhouse conditions, which approximate those generally used in horticultural practice. Color references are made to The 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London, 4^(th) Edition, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to be basic characteristics of ‘Dozanmaca’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

1. Numerous, small, and dark purple colored spathes;

2. Greyed-purple leaf margin; and

3. Highly contrasting yellow colored spadix.

Table 1 provides a comparison of ‘Dozanmaca’ to its parents, as well as Zantedeschia sprengeri variety ‘Black Star’ (U.S. Plant Pat. No. 14,844).
